I got an actual pH meter finally!

Nutrient mix was adjusted to 6.5 going in and the runoff ended up at 5.9

I need to flush. The next feeding is already set for 100% h2o. The ladies typically share 2 gallons of water between the 4 of them, a half gallon each. Now, I just need to know how much to water it, and what is the best water to flush with.

I have both distilled and R/O water. I was thinking about flushing with 2 gallons of water (1 gal. distilled, 1 gal. R/O) to each pot. (pots are 5 gal.) Should I add all of the 2 gal. at once? Over an hour? A couple hours? I have a feeling that flooding a plant like that would do more harm than good. BUT, I don't know shit about this, I have never flushed before.

What about the pH of the water? where should I aim for going in? 7.1, to even the 5.9 out to 6.5? Or pH starting @ 6.5? Also, I've heard that R/O can be harmful to soil by leaching out the nutrients due to it's "0 qualities" Or was that hydro?

Either way....I need some help.
